“…Many factors influence the increase of agricultural productivity, among others are improved crop varieties, more advanced land preparation, increased application of (mineral) fertilisers and better post-harvest processing in addition to environmental factors such as water, temperature, light, atmosphere, nutrients, fire and grazer (Haferkamp, 1988). The current development of this method called the system of crop intensification (SCI) (Abraham et al, 2014), and System Rice Intensification (SRI) designed special for rice that is being developed in Indonesia (Suciati et al, 2014).…”

Government of Indonesia has been deciding a policy of agricultural development by means of intensification for more than four decades. This development brought about environmental pollution together with productivity improvement due to a massive use of fertiliser (mainly nitrogen) and pesticides. The objectives of this study were to examine the efficiency of nitrogen and its lost to the environment, to estimate its environmental impacts and their mitigation measures. Nitrogen mass-balance models were developed to determine production, efficiency and the nitrogen losses. The results showed the trend of the system, increased the lost and decreased the efficiency of nitrogen fertiliser around 1968 and 2008. The material balance model outputs predicted that around 140 kg N/ha.year in 2008 were lost and entering the environment or ecosystem. The future of Indonesian agriculture will be more intensive and fertiliser application will increase. Fertiliser impacts are decreased of nitrogen efficiency, soil organic matters, macro-elements and organisms, and groundwater contamination and air pollution. It is strongly recommended that the future of Indonesian agricultural development should sustain the production by optimising the input and cut the losses.

Owing to population growth, the rice demand in Indonesia has been increasing, which has led to an increase in rice consumption. One way to boost rice production is to enhance pump irrigation in rainfed fields. The aim of this study is to evaluate irrigation water usage and water pumping practices in the Bengawan Solo River, focusing on enhancing rice production. Data were sourced from governmental entities, which include the Indonesian Bureau of Meteorology, Climatology, and Geophysics and the Ministry of Public Works and Housing. Water requirement was calculated using the FAO Penman–Monteith equation. The study highlights that throughout the three distinct growing seasons (GS), the water requirements for irrigating rainfed rice fields vary, with the most substantial demand observed during the first growing season (GS I), followed by the third growing season (GS III), and the second growing season (GS II). In dry years, a consistent pattern of low water balances occurs, which persists below 500 mm across all months. Compared with the other two scenarios, the dry year shows higher variability in rainfall, as evidenced by its higher coefficient of variation of 0.620 compared with 0.347 and 0.416 for the wet and normal years, respectively. The electricity cost rate peaks in GS I, trailed by GS II and GS III, with rates of IDR 2,400, 1,180, and 1,028 per kilowatt-hour, respectively. The findings play a pivotal role in shaping regional planning decisions regarding the utilization and necessity of river water resources and the development of cropping calendars.
